[0032] Embodiment 1

[0033] As Figures 1 to 2 shown, in this embodiment, an inflatable support member 100 for a vehicle seat is provided. The inflatable support member 100 is laid and installed on the vehicle seat 200. The inflatable support member 100 includes a lumbar support 1, a connecting pad 2, and a leg rest 3. The connecting pad 2 includes a lumbar support connecting portion 21, a seat cushion portion 22, and a leg rest connecting portion 23 that are connected in sequence. The lumbar support 1 is connected to the lumbar support connecting portion 21, and the leg rest 3 is connected to the leg rest connecting portion 23. The lumbar support 1 is configured with a first air pump 11, and the first air pump 11 can independently adjust the gas volume of the lumbar support 1. The leg rest 3 is internally provided with a second air pump 31, and the second air pump 31 can independently adjust the gas volume of the leg rest 3.

[0034] Among them, the lumbar support 1 is generally arranged at the backrest of the vehicle seat 200 to provide lumbar support for the occupant. The occupant can adjust the supportiveness of the lumbar support 1 by adjusting the inflation volume of the first air pump 11. For example, when a softer support is needed, less gas can be filled or a certain amount of gas can be released. When a harder or higher support is needed, more gas can be filled through the first air pump 11. The first air pump 11 can use an electric air pump that has both inflation and deflation functions.

[0035] For the convenience of folding and storage, the side of the leg rest 3 is fan-shaped, and the leg rest 3 is provided with folding pleats 32. When the leg rest 3 deflates, it will naturally fold along the folding pleats 32 under the action of gravity. After the entire leg rest 3 deflates, it is stored under the seat, without interfering with getting on and off the vehicle daily and normal sitting postures. A preferred implementation is to set the folding pleats 32 as spaced concave folding pleats and convex folding pleats (not shown in the figure). Through the spaced arrangement of the concave and convex, the leg rest 3 can be stored more neatly and beautifully.

[0036] As Figure 2As shown, the second air pump 31 is arranged at the outer edge of the leg rest 3. The outer edge of the leg rest 3 refers to the edge farther from the sector center axis of the leg rest 3. When the leg rest 3 is in the natural hanging state without inflation, the leg rest 3 where the second air pump 31 is located can be received under the bottom of the vehicle seat 200. On the contrary, when the area closer to the sector center axis of the leg rest 3 is folded, the second air pump 31 will contact the vehicle seat 200 and cannot be received more covertly, thus affecting the riding experience.

[0037] The inflatable support member 100 further includes a connecting webbing 4. Both ends of the connecting webbing 4 are fixed on the inflatable support member 100. A detachable movable fixing member 5 is provided in the middle section of the connecting webbing 4. The connecting webbing 4 fixes the inflatable support member 100 on the vehicle seat 200. In terms of specific fixing methods, the following methods can be included:

[0038] First, one end of the connecting webbing 4 is fixed in the area of the inflatable support member 100 close to the lumbar support connection part 21. Starting from this, it passes through the gap between the vehicle backrest and the seat cushion, and the other end of the connecting webbing 4 is fixed to the area of the inflatable support member 100 close to the leg rest connection part 23;

[0039] Second, one end of the connecting webbing 4 is fixed in the area of the inflatable support member 100 close to the lumbar support connection part 21. Starting from this, it passes through the gap between the vehicle backrest and the seat cushion, and the other end of the connecting webbing 4 is fixed to the leg rest 3 of the inflatable support member 100;

[0040] Third, one end of the connecting webbing 4 is fixed in the area of the inflatable support member 100 close to the lumbar support connection part 21. The connecting webbing 4 bypasses the rear part of the vehicle backrest and returns to fix the other end of the connecting webbing 4 to the area close to the lumbar support connection part 21, that is, the lumbar support connection part 21 of the inflatable support member 100 is fixed on the vehicle seat 200 through the connecting webbing 4;

[0041] Fourth, one end of the connecting webbing 4 is fixed on the leg rest connection part 23 or the leg rest 3 of the inflatable support member 100. The connecting webbing 4 bypasses the rear part of the vehicle backrest and returns to fix the other end of the connecting webbing 4 to the leg rest connection part 23 or the leg rest 3, that is, the leg rest connection part 23 or the leg rest 3 of the inflatable support member 100 is fixed on the vehicle seat cushion through the connecting webbing 4.

[0042] The fixing method includes either any one of the four aforementioned methods, or a combination of multiple methods, and also includes other methods of fixing the inflatable support member 100 on the vehicle seat 200 that do not require creative labor.

[0043] The movable fixing member 5 can be in the form of snap fasteners, Velcro, straps, hook fasteners, buttons, etc. In this embodiment, as Figures 4 - 5As shown, the movable fixing member 5 is a plug-in buckle 6. The middle section of the connecting webbing 4 is detachably connected through the male buckle 61 and the female buckle 62 of the plug-in buckle 6. A D-ring for adjusting the length of the connecting webbing 4 is provided on the male buckle 61 and / or the female buckle 62.

[0044] The top of the connecting pad 2 of the inflatable support member 100 is provided with a breathable mesh 24. Specifically, the breathable mesh 24 can be provided at any one or more of the lumbar support connecting portion 21, the seat cushion portion 22, and the leg rest connecting portion 23 to enhance the breathability during use. The bottom of the seat cushion portion 22 is provided with an anti-slip structure, and the anti-slip structure can be an anti-slip glue, anti-slip pattern, suction cup and other structures.

[0045] As Figures 2 - 3 shown, at least one of the leg rest 3, the leg rest connecting portion 23 of the inflatable support member 100 and therebetween is provided with a rigid interlayer 7. The rigid interlayer 7 can be provided inside the leg rest 3, or inside the leg rest connecting portion 23, or between the leg rest 3 and the leg rest connecting portion 23. It can be either any one of the aforementioned methods alone or a combination of multiple methods. The rigid interlayer 7 makes the appearance of the inflatable support member 100 more regular, and can evenly disperse the pressure when under pressure during use, extending the overall service life.

[0046] As Figures 6 - 7 shown, a matching adapter connector 8 is provided at the bottom of the lumbar support 1 and the top of the lumbar support connecting portion 21 of the inflatable support member 100. The lumbar support 1 and the lumbar support connecting portion 21 are detachably connected through the adapter connector 8. In this embodiment, the adapter connector 8 can be a zipper, button, snap, Velcro, strap and other structures. When the lumbar support 1 needs to be used alone, the lumbar support 1 can be separated from the lumbar support connecting portion 21 for separate use.

[0047] Embodiment 2

[0048] In this embodiment, a number of elastic tension ribs are distributed inside the leg rest 3. When the leg rest 3 is in an uninflated state, the leg rest 3 automatically closes under the action of the internal elastic tension ribs and naturally droops under the action of gravity. One end of the elastic tension rib can be provided at the top near the outer edge of the leg rest connecting portion 23, and the other end can be provided at the bottom near the vertical surface of the leg rest 3 away from the leg rest connecting portion 23 and close to the vehicle seat 200, so that the top surface of the leg rest 3 folds down and is stored along the fan-shaped center axis.

[0049] The elastic tension ribs can also be arranged parallel to the fan-shaped center axis on the inwardly recessed folding pleat 32, as Figure 2As shown, one end of the elastic tie is arranged on the inwardly sunken fold 32 on the same side as the second air pump 31, and the other end of the elastic tie is arranged on the inwardly sunken fold 32 on the side opposite to the second air pump 31; and one end of the elastic tie is arranged on the axis of the fan-shaped circle, and the other end of the elastic tie is arranged on the fold 32 relatively far from the axis of the fan-shaped circle. The distribution position of the elastic tie is not limited to the aforementioned methods, as long as the fold 32 has a certain inward force, so that the leg support 3 is flat and beautiful when folded and stored.
